Exploring Logic Gates in Digital Electronics

What is a logic gate?

• A logic gate is a component that stores electrical energy.

• A logic gate is a type of physical switch used in homes.

• A logic gate is a device that performs a basic logical function in digital circuits.

• A logic gate is a software program that manages data.

Name the basic types of logic gates.

• AND, OR, NOT, NAND, NOR, XOR, XNOR

• ADD, SUBTRACT, MULTIPLY

• INPUT, OUTPUT, PROCESS

• TRUE, FALSE, MAYBE

What is the function of an AND gate?

• The function of an AND gate is to output false only when all inputs are false.

• The function of an AND gate is to output true if at least one input is true.

• The function of an AND gate is to output true only when all inputs are true.

• The function of an AND gate is to output true when none of the inputs are true.

How does an OR gate operate?

• An OR gate outputs false if at least one input is true.

• An OR gate requires all inputs to be true to output true.

• An OR gate outputs true if at least one input is true.

• An OR gate outputs true only if both inputs are true.

What is the output of a NAND gate when both inputs are true?

• false

• high

• true

• undefined

Explain the function of a NOT gate.

• The function of a NOT gate is to invert the input signal.

• The NOT gate outputs the same signal as the input.

• The NOT gate amplifies the input signal.

• The NOT gate combines multiple input signals.

What is the difference between an AND gate and an OR gate?

• An AND gate requires all inputs to be true for a true output, whereas an OR gate requires only one input to be true for a true output.

• An AND gate requires no inputs to be true for a true output, while an OR gate requires all inputs to be true.

• An AND gate can have multiple true outputs, whereas an OR gate can only have one true output.

• An AND gate outputs true if at least one input is true, while an OR gate outputs true if all inputs are true.

How many inputs can a typical logic gate have?

• 1 to 2 inputs

• 2 to 4 inputs

• 5 to 10 inputs

• No inputs

What is a truth table?

• A truth table is a method for solving mathematical equations.

• A truth table is a diagram used for graphical representation of data.

• A truth table is a type of computer programming language.

• A truth table is a table that shows all possible truth values for logical expressions.

How do you represent a logic gate in a circuit diagram?

• Logic gates are represented by standardized symbols in circuit diagrams.

• Logic gates are represented by text labels in circuit diagrams.

• Logic gates are represented by numbers in circuit diagrams.

• Logic gates are represented by colors in circuit diagrams.
